What Are Country Style Mashed Potatoes?

Country-style mashed potatoes are known for their signature rustic nature. The potatoes aren’t super well mashed and even have bits of peels throughout every bite. As a result, they’re not the typical silky smooth mashed potatoes, but that doesn’t make them any less creamy or rich.

For decadence, whole milk, sour cream, heavy whipping cream, and even mayonnaise are added in some cases. Aside from that, every recipe is pretty much the same until you get to the seasonings. Ranging from garlic to paprika and dill, this is where the flavorful magic happens.

Recipe Ingredients

All it takes are 6 ingredients to achieve these spectacularly creamy mashed potatoes. For full ingredient amounts, check the recipe card at the bottom of the post.

  • Red potatoes – Yukon Gold and Russet potatoes are okay too.
  • Butter – Use salted or unsalted. If using salted butter, reduce the amount of salt in the recipe.
  • Garlic – Fresh and roasted garlic is my favorite. You can also use 1 1/2 tsp garlic powder instead.
  • Water – Chicken broth works great too.
  • Sour cream – Whole milk and heavy whipping cream are good substitutes.
  • Salt and pepper

What Are The Best Potatoes To Use?

Red potatoes are best for mashing because they’re starchier and absorb all the fats and liquid very well. On the other hand, it’s more difficult for them to become rubbery during the cooking process— unlike Yukon Gold and Russet potatoes.

How to Make Slow Cooker Country Style Mashed Potatoes

With the slow cooker’s help, making mashed potatoes has never been easier.

  • Add the ingredients. Place the potatoes, butter, garlic, and water in the slow cooker.
  • Cook. Cover with the lid and cook on “High” for 4 hours or “Low” for 6-7 hours.
  • Add sour cream. Remove the lid and mix the sour cream in.
  • Mash them. Use a potato masher to mash the potatoes to your desired consistency. Make them as smooth or chunky as you like!
  • Serve. Season with salt and pepper to taste. Serve warm and enjoy.

Tips for Success

Follow these tips for perfectly creamy slow cooker mashed potatoes:

  • Boil the potatoes properly. If you want creamy and soft mashed potatoes, boil the potatoes properly. You should be able to cut through them with the fork.
  • Mash them hot. Don’t let the potatoes rest and cool before mashing them. The starch will solidify and harden, making the mashed potatoes feel grainy.
  • Control the cream. Don’t add it all at once or your mashed potatoes may come out too liquidy. Pour it in little by little and adjust the consistency as needed.
  • Season at the end. When food is hot, it’s harder to tell how salty it really is. Waiting until the end to season the mashed potatoes will give you a chance to nail the amount of salt and pepper added.

What To Serve with Mashed Potatoes

These are a great side to your favorite holiday meals like my Perfect Beef Wellington, Stuffed Pork Loin with Bacon and Mushrooms, and Oven Roasted Tri Tip.

With other sides like my Air Fryer Corn on the Cob and Easy Oven Roasted Vegetables the menu is also complete.

How to Store & Reheat Leftovers

Refrigerate any leftovers in an airtight container for up to 5 days. You can also freeze them in a freezer-friendly bag or container for up to 12 months. To reheat them, mix in 1-2 tsp water and pop into the microwave for 1-2 minutes or until warm.

To defrost, transfer the mashed potatoes to the fridge a night before serving them.

  1. 3 questions! You only *smashed* the garlic and didn’t mince them up? Since there’s only 3 cloves of garlic, how strong is the flavor? And lastly, I only have russet potatoes. Would that still work fine for this recipe in the crockpot? (Or do I need to adjust anything?) Sorry, guess that was 4 questions! lol I hope to make this for Thanksgiving!

      Hi Char!! Yep, just smash it. Gives it more flavor – not sure if you like the flavor of garlic, but if you do, it tastes amazing. ๐Ÿ˜€
      You can use russet potatoes, but unlike the red potatoes, russet should be peeled first because the skin is a lot tougher.
      You don’t have to adjust the time so long as you cut them up smaller – about 2-inch cubes. I hope this helps! Let me know if you need anything else. Have a very Happy Thanksgiving!!

  2. Looks delish! If I were to halve this recipe to make for just me and my husband, would I need to adjust the time in the slow cooker at all?

      Hi Jennifer! I would say to go ahead and check the potatoes at around 3 hours, if cooking on high, but check at 4 hours if cooking them on low. Hope that helps!

    At this exact time last year I had a near-fail with the mashed potatoes I was asked to bring to a post-Thanksgiving party. I had never had problems with mashed potatoes before and of course I had to be tested with 12 people expected at dinner. This year, I offered to make the salad. ๐Ÿ™‚

    I have bookmarked this recipe for the next time I make mashed potatoes. This is truly brilliant!
